Story: the main character is about to start a new project. Then
suddenly he remembers that he wrote a similar routine for another
project 10 years earlier. He then starts dreaming about all the
software he wrote in his life as a developer.

He first sees in an accelerated motion all computers he ever
worked on – small ones, big ones, terminals, embedded systems...

...His vision starts to slow down and moves to excerpts of
software he wrote: some Fortran code on punched cards. Yes, that sort
routine was so neat, if only I still had these cards...

... Some Basic on perforated listing paper, [the code starts to
appear in mid-air], some Ada...

... some assembly (6502, 6809, 8086, 68000...). The way he
implemented this complex communication protocol in 6809, that could be
really useful today...

... some PL/1, some APL, some LISP, some Smalltalk, some Z, pure
lambda calculus, some C, some C++ [the precise list and order of it
should be decided depending on what excerpts can be found]. If only he
could access all the code he wrote in his lifetime.

Suddenly the developer wakes up from his dream while remembering
it. He knows he coded the same function. The developer tries to shove
an 8" floppy disk in his 3"1/4 drive.
